Switch no.2 is particularly good for switching low currents and/or voltages. It is the ideal switch for A.T.E. systems where cold switching techniques are often used. Where higher power levels are involved, switch no.1 is more suitable.

Note1: Life ExpectancyThe life of a reed relay depends upon the switch load and end of life criteria. For example, for an ‘end of life’ contact resistance specification of 1 Ω, switching low loads (10 V at 10 mA resistive) or when ‘cold’ switching, typical life is approx 1 x 109 ops. At the maximum load (resistive), typical life is 1 x 107 ops. In the event of abusive conditions, e.g. high currents due to capacitive inrushes, this figure reduces considerably. Pickering will be pleased to perform life testing with any particular load condition.

Washability (Proper drying process is recommended) Fully Sealed

Environmental Specification/Mechanical CharacteristicsIn the table below, the upper temperature limit can be extended to +125 °C if the coil drive voltage is increased to accommodate the resistance/temperature coefficient of the copper coil winding. This is approximately 0.4% per °C. This means that at 125 °C the coil drive voltage will need to be increased by approximately 40 x 0.4 =16% to maintain the required magnetic drive level.

10 Key Benef its of Pickering Reed Relays

Key Benef it Pickering Reed Relays Typical Industry Reed Relays

Instrumentation Grade

Reed Switches

Instrumentation Grade Reed Switches with vacuum sputtered Ruthenium plating to ensure stable, long life up to 5x10E9 operations.

Often low grade Reed Switches with electroplated Rhodium plating resulting in higher, less stable contact resistance.

2 Formerless Coil

Construction

Formerless coil construction increases the coil winding volume, maximizing magnetic efficiency, allowing the use of less sensitive reed switches resulting in optimal switching action and extended lifetime at operational extremes.

Use of bobbins decreases the coil winding volume, resulting in having less magnetic drive and a need to use more sensitive reed switches which are inherently less stable with greatly reduced restoring forces.

Magnetic Screening

Mu-metal magnetic screening (either external or internal), enables ultra-high PCB side-by-side packing densities with minimal magnetic interaction, saving significant cost and space. Pickering Mu-Metal magnetic screen - interaction approx. 5%

Lower cost reed relays have minimal or no magnetic screening, resulting in magnetic interaction issues causing changes in operating and release voltages, timing and contact resistance, causing switches to not operate at their nominal voltages. Typical industry screen - interaction approx. 30%

SoftCenter™ Technology

SoftCenter™ technology, provides maximum cushioned protection of the reed switch, minimising internal lifetime stresses and extending the working life and contact stability.

Rigid hard moulded reed relays result in significant stresses to the glass reed switch which can cause the switch blades to deflect or misalign leading to changes in the operating characteristics, contact resistance stability and operating lifetime.

100% Dynamic Testing

100% testing for all operating parameters including dynamic contact wave-shape analysis with full data scrutiny to maintain consistency.

Simple dc testing or just batch testing which may result in non-operational devices being supplied.

100% Inspection at Every Stage of

Manufacturing

Inspection at every stage of manufacturing maintaining high levels of quality.

Often limited batch inspection.

100% Thermal

Cycling

Stress testing of the manufacturing processes, from -20°C to +85°C to -20°C, repeated 3 times.

Rarely included resulting in field failures.

Flexible

Manufacturing Process

Flexible manufacturing processes allow quick-turn manufacturing of small batches.

Mass production: Usually large batch sizes and with no quick-turn manufacturing.

Custom Reed Relays

Our reed relays can be customized easily, e.g. special pin configurations, enhanced specifications, non-standard coil or resistance figures, special life testing, low capacitance, and more.

Limited ability to customize.

Product Longevity

Pickering are committed to product longevity; our reed relays are manufactured and supported for more than 25 years from introduction, typically much longer.

Most other manufacturers discontinue parts when they reach a low sales threshold; costing purchasing and R&D a great deal of unnecessary time and money to redesign and maintain supply.
